Evaluation of Correlation Between Phenomenological Approach and Fracture Mechanics Approach for Asphalt Concrete Fatigue Performance

Phenomenological approach and fracture mechanics approach are generally used to estimate the fatigue performance of asphalt concrete. The objective of this paper is to evaluate the relationship between these approaches and to characterize the fatigue behavior using fracture parameters. A series of Indirect Tensile Tests (IDT) and Disk-shaped Compact Tension Tests (DCT) were conducted to obtain the Dissipated Creep Strain Energy (DCSE) and Fracture Energy (FE) of hot mix asphalt (HMA) materials. The fatigue life (Nf) and Plateau Value (PV) of asphalt mixture was also estimated using four point bending beam fatigue tests which is a widely used phenomenological approach. Four different asphalt mixtures were investigated. Test results indicate there is a correlation between fracture parameters and beam fatigue results.
